To all whom 'it may concern Be it known that I, ANDERSON citizen of theof Findlay, State of Ohio, have invented a certain new and usefulExcavator; and I do hereby de- C. HECK, a

clare the following to be a full, clear, and

exact description of the invention, such as will enable others skilledin the art towhich it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the characters ofreference marked thereon, which form a part of this specification.`

My invention relates to excavators. 'It is applicable to a variety offorms of excavators, such as rotary or wheel excavatorsuor excavators,and in fact the invention may be contained in a great variety ofconstructions. i' The invention consists in providing a other propellingmeans on the propelling means and buckets located spaced relation toeach 1n a stepped and other. y y The invention also consists inproviding a means for carrying a plurality of removable buckets locatedcross se the path of the propelling means to produce varying widths ofexcavation,

The invention also consistsin providing a means which will enablethematerial to be removed from the buckets. structure containing theinvention is illustrated in the drawings. Thisparticular construction isshown and described to illustrate the practicability of the invention.The particular structure shown can be greatly modified and yet suchconstructions may still contain the invention. I

In the drawings, Figure is a side view of a part of a wheeliiifconnection with which the invention may be used. Fig. 2

inner` edges of the said Hange's. The bucket 65 cutters 6 are.semicylindrical and are disposed in 'spaced relation alon the` outer edes of the said flanges. Their edges are bo ted to the flanges or securedin auny other way desired which will permit their remova. 70

bility.v rlhe bucket cutters .6 have sharp edges l2foreutting the soil.They may be provided with rooters 13 which have u turned Asharl'ienededges whichidlg into t e soil. They Yare ea@ tom ltwhich closes one endofthe semiA cylindrical bucket. The buckets f7; are also provided with asharp cutting edge 15. r1`he buckets 7 are` also semicylindrical and aresecured at one side to the Bange 8 on one' side so of the Wheel andtothe Harige 9 on/the other side of the Wheelby means of bolts or othermeans permitting the removability of the buckets. .They are arranged instepped relation to the buckets 6 and along the periphery 85 I of thewheel. Either or both sets of side buckets may be removedv andv sidecutters shown in Fig. 4, may be inserted intplace of the 'side buckets.,The knives 18 have Harvv ing or spoon shaped blades and are secured 90Vto the anges 8 and 9 by means' of bolts or oth er means which willpermit their removability. The knives 18 cutaspace for clearance of therack 4 to prevent the same from entering the lsoil and becoming Iclogged. 95

en a set of side buckets' and aA set of 'ives are used the side buckets7 and knives. oppositely on the wheel and alternately with respect tothe buckets. 6

along its periphery. I 'have thus provided 100` a means whereby threedifferent widths of excavation may be made by the same excavatoraccording to the arrangement of the buckets and cutters placed upon thewheel.-`

One side of each bucket 6 1s open through '105 y which the material isfree to fall when a bucket reaches a lcertain point in the rota- Ashield 20 extends to a point where the buckets begin to turn over andprevents the contents of the buckets be- 11 The excavating wheelcomjrises a pair of provided with a bot- 7s ing lost'. The bottom 14 ofeach bucket 6 extends tothe shield 2O `and thus prevents loss of thematerial until the bucket reaches the upper end of the shield 20 whenthe material drops from the buckets. The flanges 8 and 9` slant outwardfrom the bucket to' enable the material contained therein to drop out ofthe bucket and to fall from the bucket at the upper end of the shieldv20. The buckets 7 also bein formed of a semicircular plate permit te4material to fall when it reaches'a certain, point in the rota- `tion ofthe wheel.. The bottom s17 of the buckets 7 extend to the shield 21. Theshields 21 operate in the same way that thel shield 20 operates Vto-prevent the soil gathered by the buckets 7 being lost until the soildrops over the upper edge of the shield 21. The upper edge of theshieldsv 20 and 21 extend over a belt conveyer 25. The belt conveyer maybe propelled byany suitable propelling gearor device such that it will.carry away the soil as it fallsv from the buckets 6 and 7. lWhat Iclaim as new, and desire to secure by Letters Patent is as follows:

1. In an excavator, Ithe combination of a wheel having flanges, theouter edges of the said flanges being inclined toward each other,buckets comprising semi-circular sheets removably secured to the saidflanges", side buckets located alternately to the rst veyer forconveying named buckets and along the' periphery of the said wheel andremovably secured to one of the said flanges.

2. In an excavator, Wheel having `fianges,

other, buckets comprising semicircular sheets removably secured tothesaid flanges, said buckets located alternately to the first namedbuckets and along the periphery of the said wheel and removably securedto the said flanges, shields' extending along the inner edges of theflanges and from a point below the horizontal diameter of the wheel tothe dumping point of the bucket, aconthe material from the said buckets.l

3.` In an excavator, the combination ,of an excavator wheel, a pluralityof` buckets secured to the said wheel,aplural1ty of side buckets locatedalternatelyvto the'rst named bucketsand along the'periphery 'of the saidwheel, clearance knives located on the side opposite tothe said sidebuckets vand alternate with the first named buckets..

In testimony whereof', I have `hereuntov this specification in thesigned my name to presence of two subscribingwitnesses.
